Who am I?

Coming from the world of discrete mathematics and algebraic logic, I like working on original applications of discrete probabilistic models to Knowledge Representation, Natural Language Processing and related areas in Information Science like Text Mining and Information Retrieval. The goal is to find efficient algorithms to handle discrete aspects of texts like syntax, linguistic rules and underlying conceptual structure.

Foreign language: English.

Teaching history

I am currently a permanent lecturer at the Institute of Technology of Avignon in the department of Statistics and Decision Support Systems (StID). Before coming to Avignon in 2006, I was appointed as an assistant lecturer first in 2000 at the Institute of Technology 2 in Grenoble, then in 2001 at the University Claude Bernard - Lyon 1, and in 2002 I was nominated as lecturer at the Institute of Technology of Metz.

I'm teaching Computer Science, Information Systems and Data Mining to both under- and postgraduated students in Avignon (StID and masters of computer science and Digital Governement) and in Lyon (Masters of Applied Mathematics). These lectures address the following topics:

Extended summaries in French and students notes are available at

Research activities

My research interests revolve around Discrete Mathematics, Knowledge Discovery, Natural Language Processing (NLP), Information retrieval and Cultural Heritage.

The phd's I supervised over these topics are listed in

Before these projects, I have been working on the theoretical side using algebraic logic formalism:
